Privacy Policy

1. Scope

This Privacy Policy applies to Flak Line for Android and to support communications related to the game.

Google Play, Google Payments, device operating systems, and other platform services may process information under their own privacy policies when you install, update, or make an optional purchase.

2. Information We Collect

The current release of Flak Line is designed to work without Red Yarn Games account registration, in-app user profiles, advertising SDKs, analytics SDKs, or a Red Yarn Games backend account or purchase server.

Ordinary gameplay is handled on your device. Flak Line does not request access to your camera, microphone, contacts, photos, precise location, or external storage. The Android app includes internet and network-state access so that Google Play Billing can display store products, process optional purchases, restore eligible ownership, and complete purchase acknowledgement or consumption.

The game stores gameplay progress, settings, scores, unlocked stages, selected language and mode, Gold, upgrades, owned non-consumable products, and similar game state locally on your device. It also stores a random per-install secret and up to 256 salted SHA-256 fingerprints of processed purchase tokens to protect the local game economy and reduce duplicate fulfillment. Raw purchase tokens are used temporarily to complete Play Billing operations and are not retained in the normal game save.

For an optional purchase, the app receives limited purchase data from Google Play, including the product identifier, purchase state, purchase token, acknowledgement or consumption state, and signed purchase payload fields. The app checks those fields and fulfills the product locally. It sends Google Play a one-way, hashed per-install identifier for purchase fraud correlation; the underlying local secret is not sent. Flak Line does not receive or store your full payment-card number.

Google Play and Google Payments may process your Google account, device, payment, transaction, tax, refund, and fraud-prevention information under Google's policies. Red Yarn Games does not receive this information from a separate Red Yarn Games payment server and does not upload gameplay or purchase records to a Red Yarn Games backend in the current release.

If you contact us for support, privacy, legal, or app store questions, we may receive the information you choose to include, such as your email address, device or app details, store details, attachments, and the contents of your message.

If you visit the Red Yarn Games website, hosting and infrastructure providers may process standard technical request data such as IP address, user agent, referrer, page URL, and request timestamps for normal web delivery, logging, security, and availability.

3. How We Use Information

We use local game and purchase state to provide the game experience, preserve progress, deliver purchased content, restore eligible non-consumable ownership, prevent duplicate fulfillment, and protect the local game economy. Purchase information sent to Google Play is used to request products, complete transactions, acknowledge or consume purchases, and support fraud prevention.

We use information you voluntarily send us to respond to support and privacy requests. Website technical data is used to deliver the site, maintain availability, prevent abuse, troubleshoot issues, protect our rights, and comply with legal obligations.

We do not use ordinary app activity to create advertising profiles or to make decisions that produce legal, credit, employment, housing, insurance, medical, or similarly significant effects.

4. Sharing and Service Providers

We do not sell personal information. The current release does not provide app-user personal information to advertising or analytics partners for ordinary gameplay.

We use Google Play and Google Payments for app distribution, optional purchases, ownership restoration, fraud prevention, payment and account processing, tax handling, and refunds. Google processes the information needed to provide those services under its own terms and privacy policy.

We use Cloudflare to host and secure the Red Yarn Games website and an email provider to receive messages. Those providers may process limited account, message, and technical request data needed to deliver their services.

We may disclose limited information if reasonably necessary to comply with law, respond to lawful requests, enforce terms, protect rights or safety, investigate misuse, or address security and operational issues.

5. Retention and Deletion

Because ordinary app use does not require a Red Yarn Games account or server-side profile, we do not maintain app-user account data on our servers for standard use of the current release.

Local game progress remains on your device unless you delete the app, clear app data through your device settings, or overwrite that progress through normal gameplay. Android cloud backup is disabled for Flak Line. Raw purchase tokens are kept only while needed to complete or retry acknowledgement or consumption. The local save retains no more than 256 salted token fingerprints.

After reinstalling, Google Play may allow the app to restore eligible non-consumable ownership. Consumable Gold balances and ordinary game progress are not stored by Red Yarn Games for cross-device restoration. Google and other service providers keep information according to their own retention and deletion rules.

Website technical logs and support communications may be retained for as long as reasonably necessary for security, operations, responding to the request, protecting our rights, and complying with applicable law.

6. Security

Flak Line uses local integrity checks, a random per-install secret, one-way purchase-token fingerprints, atomic save replacement, and Google Play Billing purchase states to reduce accidental corruption and duplicate fulfillment. Network purchase processing is handled by Google Play. No method of local storage or electronic transmission is completely secure, and the serverless design does not provide authoritative server-side receipt validation.

7. Your Choices and Rights

You can stop using the game at any time and may remove it from your device. You can delete local game data by clearing Flak Line's storage in Android settings or uninstalling the app. Google Play settings and support channels let you manage payment methods, purchase history, eligible refunds, and platform account data.

Depending on applicable law, you may have rights to request access to, correction of, deletion of, or restriction of personal information we hold about you. To make a privacy request, contact us using the email below. We may ask for reasonable information to verify and process your request.

8. Children's Privacy

Flak Line is not intended to knowingly collect personal information from children in violation of applicable law. If you believe a child has provided personal information to us improperly, please contact us so that we can review the issue.

9. International Processing

Service providers used for website hosting, email, app-store distribution, and security may process information in countries other than where you live. Where required, we rely on appropriate safeguards or legal bases for that processing.

10. Changes to This Policy

We may update this Privacy Policy from time to time. Any updated version will be posted on this page with a revised effective date or last updated date.
